What is a Velomobile?
Over the past few years, I have often taken
a position of on-line forums over what constitutes a velomobile and some people
may not like that stand. I think that a
crop of small vehicles is falsely being referred to as velomobiles so let me
state my case. Personally, I like the
definition of velomobiles found in Wikipedia.
Quest Velomobile |
A velomobile,
or bicycle car, is a human-powered vehicle (HPV) enclosed for aerodynamic
advantage and protection from weather and collisions. Nearly all velomobiles
are single-passenger vehicles. They are derived from recumbent bicycles and
tricycles, with the addition of a full fairing (aerodynamic shell). Most
Velomobiles have three or four wheels. Fully faired two wheel roadgoing
machines are included within the more general category "human powered
vehicle" (HPV). Pedal powered faired vehicles intended primarily for racing
are usually called streamliners. Streamliners have set many speed and
distance records.
There are few manufacturers of velomobiles;
some are home-built. Some models have the operator's head exposed; this has
the advantage of giving the operator unobstructed vision, hearing, and some
cooling, with the disadvantage of being more exposed to weather and less
aerodynamic. Similar vehicles that are not human-powered are called
microcars. Hybrid vehicles exist which can use both human power and assistance
by an electric motor.

So what is wrong with saying that ELF or
the new Veloschmitt Tiger 4-Wheeler are velomobiles. For one, these were never intended to be used
without electric assist. A Velomobile is
a Human Powered Vehicle first and
foremost. When the Veloschmitt Tiger
4-Wheeler is introduced, it will apparently weight 120kg, it will not be
particularly aerodynamic and have a 15kW electric motor to propel it to 25km/h
(15mph). The ELF is also a bit weighty
at 150lb (68kg) and not very aerodynamic, has a 600W electric motor and a speed
of 20mph (30km/h) and has only a 15mi
(24km) range. When you need to
get such strong motors to reach these very sedate performances, you can only
guess that you would very strong legs to move these beasts for any distance and
on very level ground.
Compare this with an average velomobile
that weight-in at approximately 25kg to 30kg and require slightly more than
150W to travel at 40km/h. This is not
the state of the art velomobile, just a good average velomobile. A regular rider will also be able to climb
hills without electric assist.

I think it may be to the advantage of these
companies to identify themselves as velomobiles for marketing and regulatory
reasons but these in my opinion are only microcars. In the process, I think they overstate the
ability for the user to operate the
vehicle using the pedals, the aerodynamic advantage, etc. Again lets look at the definition for
Microcar and also cyclecar and in Wikipedia.
A microcar
is the smallest automobile classification, usually applied to very small cars
(smaller than city cars). Such small cars were generally referred to as
cyclecars until the 1940s. More recent models are also called bubble cars due
to their bubble-shaped appearance.
The definition of a microcar has varied
considerably in different countries. Since there are usually tax and/or
licensing advantages to the classification, multiple restrictions are often
imposed, starting with engine size. The Register of Unusual Microcars[1] in
the UK says: "economy vehicles with either three or four wheels, powered
by petrol engines of no more than 700cc or battery electric propulsion, and
manufactured since 1945". The Bruce Weiner Microcar Museum (the world's
largest collection of Microcars) says "Engine sizes of 700cc and less
and 2 doors or less" and the US-based Vintage Microcar Club simply
defines it as 1000cc or less.
A cyclecar
was a type of small, lightweight and inexpensive car manufactured mainly
between 1910 and the late 1920s. Cyclecars were characterised by their use of
basic materials and sometimes fragile engineering and were largely contrived
to fill a gap in the market between the motorcycle and the car. Their demise
was largely the result of production economies in the manufacture of more
substantial economy cars such as the Austin 7 and the consequent
affordability of such vehicles. Vehicles with similar qualities produced
after World War II, are generally categorized as microcars.
Cyclecars were propelled by
single-cylinder, V-twin or more rarely four-cylinder engines, often
air-cooled. Sometimes these had been originally used in motorcycles and other
components from this source such as gearboxes were also employed. Cyclecars
were halfway between motorcycles and cars and were fitted with lightweight
bodies, sometimes in a tandem two-seater configuration and could be primitive
with minimal comfort and weather protection. They used various layouts and
means of transmitting the engine power to the wheels, such as belt drive or
chain drive often to one rear wheel only to avoid having to provide a
differential.

If you look at these definitions, you
notice that they very well describe todays offering except that they now offer
pedal assist to increase range and performance.
E-Scooter with pedals |
Few
people would consider an E-Scooter as a bike but they sport pedals to be
considered as bikes providing them access to MUPs, no-licensing requirement,
etc. While this may be intent, very few
people ever use the pedal. In addition,
several cities have reacted by banning them from the cycling infrastructure.
The fact that a vehicle has some of the
characteristics of a velomobile does not automatically make them
velomobiles. I must be clear that an
electric e-assist would not make a regular velomobile a microcar because as the
name states, the system is to assist the rider in certain situations like hill
climbing where the rider may not have the strength required to make it all the
way up on his own. The e-assist should
not turn the velomobile into a vehicle that cannot be easily pedaled by an
average rider over long distances.
If you want to purchase a velomobile, be
ready to pedal most of the time, otherwise purchase a Microcar that may be
equipped with pedals. Let’s call a
spade, a spade!
